So far as we are human, what we do must be either evil or good: so far as we do evil or good, we are human: and it is better, in a paradoxical way, to do evil than to do nothing: at least we exist.
(T.S. (Thomas Stearns) Eliot (1888-1965), Anglo-American poet, critic. repr. In Selected Prose of T.S. Eliot, ed. Frank Kermode (1975). "Baudelaire," introduction, The Intimate Journals of Charles Baudelaire, trans. by Christopher Isherwood (1930).)
But what is the greatest evil? If you are going to epitomize evil, what is it? Is it the bomb? The greatest evil that one has to fight constantly, every minute of the day until one dies, is the worse part of oneself.
(Patrick McGoohan (b. 1928), Anglo-American actor. Quoted in Dave Rogers, "I Am Not a Number, I Am a Free Man," The Prisoner and Danger Man (1989).)
